The Mooncup is a reusable menstrual cup around two inches long and made from soft silicone rubber. It is worn internally like a tampon but collects menstrual fluid rather than absorbing. Unlike tampons the Mooncup is not a disposable product, so you only need to buy one. The Mooncup will hold 30ml of fluid, which is roughly one third of the average total produced each period. A light seal is formed with your vaginal walls allowing your menstrual fluid to pass into the Mooncup without leakage or odour. You will probably find that you need to empty your Mooncup less frequently than you currently replace towels or tampons. The Mooncup is available in two sizes. Size A measures 46mm in diameter and 50mm in length. Size B measures 43 mm in diameter and 50mm in length. Both sizes have a pull stem 21mm long, which you can trim to the length that is right for you. Size A is recommended for women who have given birth vaginally or who have had a caesarean section and are aged 30 or above. Size B is recommended for women who have not given birth or who have had a caesarean section and are aged below 30. Please ensure that you select the correct size. For hygiene reasons we cannot exchange Mooncups once they have been dispatched. Ingredients made from soft silicone rubber
